SIGNAL-LAMP.

SPECIFICATION forming part of Letters Patent. No. 714,564, dated November 25, 1902. Application filed September 9, 1902. Serial No. 122,647. (No model.)

To aZZ whom it may concern.-

Be it known thatI, CHARLES H. Dnnssun, a citizen of the United States, residing in the borough of Manhattan, city, count-y,and State of New York, have invented an Improvement in Signal-Lamps, of which the following is a specification.

My invention relates to lamps, and particularly to signal-lamps such as are usually employed upon railroads and in which an oilfont and burner are used having the shaft of the wick-raiser extending through the body of the lamp for externally regulating the height of the flame. l-Ieretofore difficulties have been experienced in closing from the influence of currents of air the opening in the lamp-body through which the wick -raiser shaft passed; and my invention consists in an improved means for closingthe aperture in the lamp-body through which the wickraiser shaft passes and at the same time engaging the said shaft to hold the oil-font securely in place within the lamp-bodyand which means for closing the aperture makes the same practically wind-proof.

In carrying out myinvention I employ upon the outside of the lamp-body a pair of arms pivoted one outside the other adjacent to the aperture in the lamp-bod y through which the wick-raiser shaft and the operating button or head thereon passes. The lower part of the aperture is recessed to receive the said shaft, and the pivoted arms are provided with semi- .circular notches adapted to fit around and engage the shaft when the lamp is in position and the arms are brought together and close ofi the aperture in the lamp-body.

In the drawings,Figure 1 is an elevation and 1 partial section of my improved signal-lamp.

Fig. 2 is an elevation of the parts for closing the aperture, the parts being shown in the opened-out position. Fig. 3 isa similar view with the parts in a closed position, and Fig. 4 is a horizontal section on the line 00 m of Fig. 3 in larger size;

a represents a lamp-body having an aper- The lamp-body a is provided with a suitable base I), which may be adapted to fit a standard when the lamp is employed as a switch-signal. The lamp-body a is also provided with a hinged or other coverc and suitable lenses cl.

e represents an oil-fon t, f the burner of the lamp employed in the lamp-body a, 3 the wick-raiser shaft connected to said burner and on the outer end of which is the usual operating-button. The font is placed in the lamp at the upper end when the cover is raised and as the parts are brought to position. The wick-raiser shaft 3 and operatingbutton are passed through the aperture 1 in the lamp-body, and the shaft fits within a recess 2, provided at the lower part of said aper-.

ture.

4 5 represent similar but reversed arms which are pivoted to the exterior of the lampbody at 6, the one outside the other above the aperture 1. The arms 4 5 are provided with semicircular recesses 7 and 8 in such a position that when the arms are closed they extend over and close off the aperture 1, and said recesses fit around and engage the wickraiser shaft 3. The arm 5 is provided with a depressed portion 9, adapted to fit closely to the exterior of the lamp-body a, and both the pivoted arms at and 5 are provided with lugs 11,- by which they may be easily opened and closed. By this structure the lamp-body is substantially wind-proof, and the oil-font within the lamp-body is held securely in place bythe shaft 3 being engaged by the recesses in the lamp-body and pivoted arms, and the height of the flame may be regulated exteriorly of the lamp-body by turning the operating-button 10, secured to the end of the wickraiser shaft 3.

The adjacent edges of the arms 4 5 may, as

shown, be made with inwardly-curved parts 12 13, made on the same are as the edge of the aperture 1, their office being to obviate the necessity of opening out the arms so far when the operating-button and shaft are passed through the aperture 1. Y

I claim as my invention- 1. A signal-lamp, comprising a lamp-body having an aperture with a marginal recess therein, an oil-font and a burner, a wickraiser shaft and operating-button passing through said aperture with the shaft received in said recess, and a pair of arms pivoted to the lamp-body, the one outside the other above said aperture, and arranged to swing together to close said aperture, said arms being adapted to pass around and engage the said wick raiser shaft to maintain the same ,and'assist in maintaining the oilfont and burner in position within the lamp.

2. A signal-lamp comprising a lamp-body having an aperture with a marginal recess therein, an oil-font and a burner, a wickraiser shaft and operating-button passing through said aperture with the shaft received in said recess, and a pair of arms pivoted to the lamp-body the one outside the other above said aperture the one having a de- CHARLES H.
